Interstitial fluid flow is elevated in solid tumors and can modulate tumor cell invasion. Here we describe a technique to apply interstitial fluid flow to cells embedded in a matrix and then measure its effects on cell invasion. This technique can be easily adapted to study other systems.

A 3D system of culturing human articular chondrocytes in high levels of synovial fluid is described. Synovial fluid reflects the most natural microenvironment for articular cartilage, and can be easily obtained and stored. This system thus can be used for studying cartilage regeneration and for screening therapeutics for treating arthritis.

FAQs
Each component can affect a different aspect of cell performance. Salts and buffering agents help maintain chemical conditions, sugars provide energy, and amino acids and vitamins support cellular activity. Serum or defined growth factors may further influence survival, growth, or specialized functions. Changing this balance can therefore alter immune responses independently of the experimental stimulus.
Serum can supply growth-supporting influences, whereas a defined formulation uses specified components and growth factors. The choice affects how precisely investigators know which substances surround the cells and how readily they can interpret responses. In immunology and infection studies, this distinction matters when comparing cytokine release, proliferation, cytotoxicity, or host-pathogen interactions across experiments.
pH and osmolarity help maintain conditions compatible with cell survival and function. Buffering agents contribute to pH control, while the balance of dissolved salts and other ingredients influences osmolarity. If these conditions are poorly matched to the cells, measured changes may reflect environmental stress rather than the pathogen, microbial product, or immune stimulus being investigated.
Cells exchange metabolites and signaling molecules with their surrounding fluid, so the medium is part of the experimental environment rather than a passive container. Accumulating or changing molecules can influence neighboring cells and measured responses. Consequently, cytokine release, proliferation, cytotoxicity, and host-pathogen interaction data must be interpreted in relation to the selected formulation and culture conditions.
Selection should match the cells’ survival needs, specialized functions, and the intended experimental exposure. Investigators also need to consider whether the formulation will support contact with pathogens or microbial products and permit measurement of the chosen outcome. Aligning the fluid with the biological question helps distinguish genuine immune or infection effects from formulation-driven changes.
These experiments can examine cytokine release, cell proliferation, cytotoxicity, and changes in host-pathogen interactions. The fluid provides the environment in which immune cells encounter pathogens or microbial products, while the resulting cellular responses supply measurable evidence. Because composition influences these outcomes, consistent formulation is important for comparing conditions and assessing experimental reproducibility.
